CHAPTER 3 THEORY OF OPERATION 2.2.3 Paper eject After the printing image on the photosensitive drum is transferred onto the paper, the paper is fed to the fixing unit to fix unfixed toner onto the paper. Afterwards, the paper is ejected from the fixing unit by the first eject roller in the fixing unit. The eject sensor lever detects whether the paper is ejected correctly or not.
CHAPTER 3 THEORY OF OPERATION Sensors 2.3.1 Cover sensors A and B Detect opening and closing of the front cover. Cover sensor (B) Cover sensor (A) Fig. 3-32 2.3.2 Toner sensor Detects if there is toner in the toner cartridge. The toner sensor at the left side emits light through the window on the left side of the toner cartridge, then the toner sensor at the right side receives it when the toner is low.
CHAPTER 3 THEORY OF OPERATION Drum Unit 2.4.1 Photosensitive drum Generates the latent electrostatic image and develops the image on the drum surface. 2.4.2 Primary charger Forms a uniform charge on the drum surface. (1) Corona wire Generates the ion charge on the drum. (2) Grid Spreads the ion charge evenly over the drum surface.
CHAPTER 3 THEORY OF OPERATION Print Process 2.6.1 Charging The drum is charged to approximately 870V by an ion charge which is generated by the primary charger. The charge is generated by ionization of the corona wire, which has a DC bias from the high-voltage power supply applied to it.

CHAPTER 3 THEORY OF OPERATION The area exposed to the laser beam is the image to be printed. The surface potential of the exposed area is reduced, forming the electrostatic image to be printed. 1 Cycle of drum Primary charging Laser beam exposure and developing (a) Unexposed area +870...
CHAPTER 3 THEORY OF OPERATION 2.6.4 Transfer (1) Transfer process After the drum has been charged and exposed, and has received a developed image, the toner formed is transferred onto the paper by applying a negative charge to the back of the paper.
CHAPTER 5 PERIODIC MAINTENANCE CHAPTER 5 PERIODIC MAINTENANCE To avoid creating secondary problems by mishandling, follow the warnings below during maintenance work. WARNING (1) Always turn off the power switch and unplug the power cord from the power outlet before accessing any parts inside the printer. (2) Some parts inside the printer are extremely hot immediately after the printer is used.
CHAPTER 5 PERIODIC MAINTENANCE (4) Install the toner cartridge into the new drum unit until it locks into place, indicated by a click. When the toner cartridge is installed correctly, the lock lever is lifted automatically. (Fig. 5-2) (5) Install the new drum unit into the printer. Check that the printer is turned on, the front cover is open and the Drum and Alarm LEDs illuminate.
Page 135
CHAPTER 5 PERIODIC MAINTENANCE (4) Remove the protective cover. (Fig. 5-4) (5) Install the new toner cartridge into the drum unit until it locks into place, indicated by a click. When the toner cartridge is installed correctly, the lock lever is lifted automatically. Fig.
CHAPTER 5 PERIODIC MAINTENANCE PERIODICAL REPLACEMENT PARTS Periodical replacement parts are the parts to be replaced periodically to maintain product quality. These parts would affect the product quality greatly if they lost their function even if they do not appear to be damaged or there is no change in their appearance.) The periodical replacement parts listed below should be replaced at the service center referring to the service life.
CHAPTER 5 PERIODIC MAINTENANCE PERIODICAL CLEANING Clean the following parts periodically to avoid any printer problems or print image defects. CAUTION: While drum unit and scanner window cleaning basically can be implemented by the end user, the electrical terminals inside the printer and on the drum unit should be cleaned by a service technician.
CHAPTER 5 PERIODIC MAINTENANCE Cleaning the Scanner Window When replacing the drum unit or toner cartridge with a new one, be sure to clean the scanner window. Turn off the power switch and unplug the power cord. Remove the drum unit from the printer. Gently wipe the scanner window (colored magenta in the figures below) with a soft dry cloth.
